Building Ore Stockpiles Design

Mine stockpile design to minimise environmental impact

Putting the ore onto stockpiles before shipment serves a double purpose. The stockpiles provide a quantity buffer between the arrival of ore trains from the mine and the more irregular departure of ships. But of just as much importance is the effect of stockpiles in blending out variations in ore composition.

Building iron ore stockpiles to target grade and ...

AB - An iron ore mine prepares pre-crusher stockpiles, feeding the processing plant with ore at target composition, in grade (iron and multiple contaminants) and physical and source characteristics. Weekly, ore blocks to be mined are allocated to the previous stockpile, or to a new stockpile. By week end, the previous stockpile is completed.

Pre-crusher stockpile modelling to minimise grade variability

building sets of stockpiles (usually up to three pairs; high, me-dium and low grade) with maximum grade differential (described in detail below); adopting a grade separation method suited to the nature of the ore and the customer quality requirements to give maximum ef-fectiveness when they are being blended back together to form

Management of Tips and Stockpiles - Health and Safety ...

The ground used for the stockpiles - It should be firm and provide a stable foundation. It should be relatively level, properly drained and should not be affected by water courses, which may flood. The volume of product. - The output of a quarry will have an influence on the siting, type and size of stockpile.

Simulation Modeling of an Iron Ore Operation to Enable ...

ore quality is to produce ore of consistent grade (not only in iron, but also in phosphorus, silica, and alumina). Traditionally this is achieved by blending from intermediate stockpiles, but this imposes large handling and stock costs which would be avoided if the desired grade uniformity can be achieved with less rehandling of the ore.

Ore Stockpiling – Why are we doing this again?

Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be stockpiled during the campaigning. That means even more ore stockpiles at site. 2.

01-03-1997· Ore is sent to any one of three stockpiles being built. Changing the destination is costly, so it is reviewed only at pre-set intervals, a set fraction of a stockpile capacity. Repeat simulations in the same run can examine a range of review intervals.

GRADE CONTROL BLENDING AND SELECTIVITY FOR OPTIMAL …

Ore is reclaimed perpendicular to the tipping direction. The average grade of a particular stockpile is the average grade of ore mined during a certain stockpile building period. Ore from the stockpiles is blended to the required grade before feeding to a stacker-reclaimer for further homogenisation.

Properly managing aggregate stockpiles means overcoming challenges both old and new, though drone technology is playing a greater role in solving those problems, experts say. Among the current obstacles faced by aggregate managers, especially those who run smaller plants, is the growing number of mixes being developed and requested by clients, which means more piles on site.
